The Doppelganger Distributed Mirror System lets server owners who could mirror files but don't have the bandwidth to handle being a full mirror to contribute resources as well. Each mirror operator specifies how many times per day each package that they mirror may be downloaded. Doppelganger distributes the requests among the mirrors and pulls mirrors out of the day's rotation as they max out.

German for "Double-goer." A person's duplicate or identical counterpart, seen as a result of bi-locational or astral travel. This phenomenon has been overshadowed by the more modern (and viable) concept of cloning, with its speculative ramifications.

A boss in a game that is a clone or can make clones of the character(s) you play as. (Ex: the Shadow in Zelda 2; Dark Link in Ocarina of Time; Sage Joch's Test in Secret of Mana; the Mt. Ordeals "boss" in Final Fantasy 4; the final boss of Axelay; the Mega Man clones in MM1 and 3; the Shades boss in Koudelka; Belome in Super Mario RPG; the forest bridge boss in Secret of Evermore; the Ryu clone in Ninja Gaiden 3.)

A spirit of a living person or animal outside of the physical body. Being exact duplicates of the living person including dress, this could possibly be an projected out of body experience either consciously or unconsciously or a death omen. Typically "double-goers" are seen by others in distant locations just as the individual in question is about to die or has died.
